Image Format with History Support

When working with captured images, users need more editing options. Specifically, the following abilities are desirable:

• To capture snapshots that are made to a graphic• To revert to a specific snapshot later, with any software application that supports

the snapshots/captures • To store the images into a single image file • To go back to the original image before making changes• To go back to snapshots in-between the original and final

Most image editors allow the user to undo certain commands while editing an image. This command history is available only on the editor currently in use, and is lost when the user closes the image or the editor. Image editors allow users to work in layers or support versioning, which can be directly provided by the image-editing tool or provided by an external version control system. In any case, the history or versions are proprietary of the software used to for image creation.

A solution would be to save each graphic revision as a separate graphic and then save

all of the revisions into a compressed file, such as a ZIP file.

The novel contribution is a method to easily capture and access snapshots to an image. The method implements a new image format to make the image and store the change history independent of the editors. The new image format allows the user to preserve snapshots of the different stages of the image during the editing process. To make this functionality independent of the editor, the image is composed of fragments with a foundation layer, the canvas containing the original image, plus the delta variations from the previous states.

The idea is to work independent of editing software, but remain fully compatible with popular image formats (JPG, BMP, PNG, EPS, etc.). Therefore, if the image view...
